Red Hat Bugzilla – Bug 505357
syndaemon fills system up with threads
Last modified: 2009-06-18 07:44:58 EDT
Description of problem: This is a ThinkPad notebook with an external USB keyboard and USB mouse connected. In the mouse settings, "Disable touchpad while typing" is activated. When I disconnect the mouse or the keyboard, and then reconnect it, there are 8 new syndaemon threads running. This is, after disconnecting both the keyboard and mouse, there are 16 syndaemon threads. When disconnecting and reconnecting again, there are 32 threads, and so on... Eventually the system locks up because of the number of threads (this is, I cannot start new threads). When I log in from a remote system and invoke "killall syndaemon", everything is working again. But still, there are 8 new threads everytime I disconnect the mouse or the keyboard. This is especially annoying when the keyboard and mouse is connected via a KVM switch, because there are 16 new threads everytime I switch back from the other system. Anyhow this bug is reproducible even without a KVM switch. This bug does not occur if "Disable touchpad while typing" is deactivated. Version-Release number of selected component (if applicable): Fedora 11 x86_64, with all updates applied xorg-x11-drv-synaptics-1.1.0-7.fc11.x86_64 How reproducible: Always Steps to Reproduce: 1. Activate "Disable touchpad while typing". 2. Disconnect your USB keyboard or USB mouse, then reconnect it. 3. Count the number of "syndaemon" threads. Actual results: 8 more syndaemon threads after every reconnect Expected results: no more than one syndaemon thread Additional info: There is no xorg.conf file. I will attach the Xorg.0.log in a few minutes, but it contains no hint about syndaemon.
Created attachment 347432 [details] Xorg log file The Xorg.0.log after disconnecting and reconnecting the USB mouse.
same goes for here lots of syndaemon thread is running resuming after hibernate. Disabling in mouse preference doesnt work, had to manually kill the threads.

verified, missing check in gnome-settings-daemon's mouse plugin before activating syndaemon.
Created attachment 347884 [details] updated g-s-d support touchpad patch Patch adds three lines to set_disable_w_typing to check whether syndaemon has been started already. static int set_disable_w_typing (GsdMouseManager *manager, gboolean state) { GError *error = NULL; if (state) { char *args[4]; + if (manager->priv->syndaemon_spawned) + return 0; + args[0] = "syndaemon"; args[1] = "-i"; args[2] = "0.5"; args[3] = NULL; koji test build: http://koji.fedoraproject.org/koji/taskinfo?taskID=1414144
